Restored with wrong file after virginizing

After virginizing my 1.0.2 Iphone I accidentally restored with the iPhone1,1_1.1.1_3A109a_Restore.ipsw instead of iPhone1,1_1.0.2_1C28_Restore.ipsw.

First I only got a message about wrong SIM and iTunes needed 7.5 to unlock. Then I tried to restore it again holding down the 2 buttons on the phone. First time I tried this I didn┤t get the restore oppertunity, but the second time I got it, and tried to restore it with iPhone1,1_1.0.2_1C28_Restore.ipsw and only got an unknown error(1)

I will also add that what made me realise the, arrrgh!, mistake was when I tried to use the iNdependence 1.2.5 and got the message that I needed 1.0.2 for this.
